The usual optical beams can be described as localized (e.g., bell-shaped) waves in space with rapidly decreasing intensity at increasing distances from the beam axis. Examples of such beams are Gaussian beam and hyperbolic-secant beam (see Fig.2a), which we often denote as “bright beams”...
Redox ratio from NIR spectral range which as Y axis and redox ratio from visible (VIS) spectral range as Z axis. In order to get a 100% sensitivity, we did not take into account all the molecular ratio values in the distribution of each type, however, we took the median value of ...
. We used a InGaAs camera (OW1.7-VS-CL-LP-640, Raptor Photonics) with exposure time of 20 μs and a maximal frame rate of 120 Hz, and employed off-axis digital holography to record the complex-valued fields emitted from the fiber output facet in response to all possible MMF input...
Eq. (2) provides the rotation matrix for pan/tilt motions where the z-axis represents the principal axis, the x-axis is positive, right and the y-axis is positive, down. Pre-multiplying a set of points in global coordinates by the rotation matrix, R, then gives the new locations of ...
With this method in principal also the defocus caused by the Gaussian beam profile along the z-axis can be numerically compensated. For more details the reader may refer to the references [34,35,36]. 3.4.7 High Speed OCT Since the beginning of the clinical use of OCT imaging devices in ...
In a typical implementation, the polarisation plane of a probe beam is aligned perpendicular to the axis of a polarising element (the “analyser”), and the transmitted light intensity is recorded using a photodetector. A Faraday oscillator of frequency f perturbs the polarisation plane of the ...
2c. For the light wave polarized along the long axis (TM-polarization) the plasmon resonance is observed at 670 nm, while for light polarized along the short axis (TE-polarization) the resonance corresponds to 780 nm. Discrete Dipole Model In order to derive surface conductivity of a ...
(f) a combining optical system for combining a light beam transmitted through said first area of said index plate as a return light beam returned from said localized area through said objective optical system on the same axis; and (g) said image pickup device for detecting an image of said...
An off-axis optical display system is provided. The system comprises an eyeglass lens assembly having a first lens section having a first surface, at least a portion of the first surface having a firs
